I'll recommend two for you, depending on your needs. I haven't had them all but have had or used quite a few over the years.
Summit climbers are the most comfortable that I have found. They are preferred for LONG sits. Also they have an aftermarket seat that surrounds you which can be nice in the wintertime on windy days as it can be a wind barrier and keep you a touch warmer than a more open stand will.
Lone Wolf climbers are in my experience the most quiet and most versatile in what trees they can get into. They also seem to be built a little better overall than anything else that I have used. The downside to them is that they are not the most comfortable on the market. I put a Hunt Comfort gel core pad in mine and lean against the tree. I'm a pretty small guy and have troubles with my butt and legs going numb if I sit on hard surfaces, even like a wooden chair or stool, for more than about an hour. With the Hunt Comfort pad, I can last all day with periodic standing breaks, which I would do anyway just to stretch my legs. Because of this versatility and quality, I have since sold my Summit stands.
I now own 4 tree stands total. Two are cheap ladders that stay chained to two trees on my grandfather's land. I sit in those trees about twice a season and my father-in-law does as well. For public lands I use either my Lone Wolf hang on or Lone Wolf climber. If I know the exact tree that I want to be in will fit the climber it goes with me. Otherwise the hang on gets the nod as it's more versatile.
